A history of paleoflood hydrology in the United States
The origins of paleoflood hydrology in the United States can be traced back to the beginning of the 19th century, when windgaps and watergaps in the Applachians were believed to have been eroded by extraordinary floods as large lakes that were ponded behind the ridges rapidly drained. Sediment evidence for extraordinary floods was evoked several decades later when glacial sediments in New England

Landslides
The slopes above streams and rivers are subjected to a variety of processes that cause them
to recede and retreat from the river or stream channel. These processes, collectively called
mass wasting, can be classified according to rapidity of movement and according to the type
of materials that are transported. Gravity is the force behind all such downslope movement.
Factors that enable the force o

Geophysics: A reversal of geomagnetic polarity
The detailed behaviour of the geomagnetic field during reversals is documented by palaeomagnetists to constrain models of the geomagnetic dynamo. Reversals are studied by measuring the magnetic remanence preserved in rocks to obtain both the direction and intensity of the ancient magnetic field.
